Suction power's become an important bullet point when it comes to selling vacuums. But what really matters to consumers is how easy they are to empty. The annoying bags of yesteryear have been replaced with easy to use trapdoor canisters, which now see further improvement with Electrolux's new UltraCaptic cleaners that compress the dust into an easily disposable disc.

Besides being easier to empty, the compressor also means the UltraCaptics can hold more dirt before requiring you to visit a garbage can. And if you're into industrial-design that makes a ho-hum appliance look like a futuristic compact fusion reactor, these canister vacs have that in spades too. The basic version, the UCOrigin will set you back $390, while the most advanced in the collection, the UCDeluxe, bumps that to almost $550. [Electrolux via Appliancist]
